whats better...barton vs tbred b

[d_fresh1]

Hey all, im abt 2 purchase my new set up and i was just wondering whether i should get this:

Barton 2500 - AXDA2500DKV4D AQXEA 0327MPMW

or

XP2400 - AIUHB

help

barton.

At stock the 2500 barton runs at 333fsb and the 2400 only runs at 266fsb. The barton would be better due to the better fsb frequency, you would however need DDR333 memory to run this with the barton. (the barton also has more cache memory which makes a few % difference in certain applications)

Hope this helps explain a bit of why its better.

wot abt for ocing?

[Barry]

barton all round

[d_fresh1]

Ive got the 2400XP, cant fault it. But the barton if youve got the cash.

[Stoo]

Yup, Barton.
From what I've seen, there's only about few £ in the prices of the two anyway.

just bought it

bartionio all the way

The XP2500+ Barton only runs at 1.8ghz, the rating takes into account the 512k L2 and 333FSB so as the rating suggests it is a tad faster than the XP2400+ TbredB but has a LOT more o/c'ing headroom. All TbredB from XP1700+ to XP2700+ seem to achieve XP2700+ speeds and handle 400FSB with ease. Barton seem to dislike 400FSB a little less but I think the newest mobos address that anyway. So it's pretty pointless buying a faster TbredB, XP1700+ has plenty of room in it to get at least XP2600+ speeds (333FSB or 5th FID bit enabled mobo) so the choice is really between a low end TbredB like XP1700+ or XP1800+ (£40) and the low end Barton XP2500+ (£65). Oh BTW Bartons seem to hit around 2.1ghz with relative ease and normal voltages, so with a 400FSB able mobo you should achieve the XP3200+ speeds.

dun and dun , but i fried my Hard drive...wish they had pci, agp lock after 200 fsb

The AGP/PCI/IDE lock as found on all nForce2 isn't as useful as it's made out to be. Using dividers is more than fine so long as you don't lack one high enough for the FSB you wish to achieve. Often the chipset (etc) is more than capable of the faster FSB but without the next divider up you're stuck as things will run too far out of spec. Examples of the dividers needed for the various FSB are below.

100/200FSB 1/3 PCI=33.3mhz (ALL)
133/266FSB 1/4 PCI=33.3mhz (eg KT266-333 & SiS735-745)
166/333FSB 1/5 PCI=33.3mhz (eg KT400 & SiS746FX)
200/400FSB 1/6 PCI=33.3mhz (eg KT600 & SiS748)

When you go inbetween these settings you run out of spec but the PCI bus and all (eg AGP= 2xPCI) should be quite happy between 30mhz and 36mhz, slightly higher depending upon specifics. So the most difficult and risky thing is how far to go when your mobo lacks the desired multiplier as you can see below for the KT400 & SiS746FX which have 1/5 as the highest divider...

166/333FSB 1/5 PCI=33.3mhz
175/350FSB 1/5 PCI=35.0mhz
180/360FSB 1/5 PCI=36.0mhz (would be 30.0mhz with a 1/6 divider)
185/370FSB 1/5 PCI=37.0mhz (would be 30.8mhz with a 1/6 divider)
190/380FSB 1/5 PCI=38.0mhz (would be 31.7mhz with a 1/6 divider)

In the same way a KT600 or SiS748 max out with a 1/6 divider so are only safe (as can be) up to around 216/432FSB where 1/6=36mhz. Of course speeds above 200/400FSB carry VERY minimal gains for SktA anyway, so this shouldn't be limiting. Also bear in mind what speed your RAM is running. It's usually equal to the FSB but could be set by ratio which is what enables for eg the KT400 to run the RAM at 333mhz (5:4) or 400mhz (3:2) when the FSB is set to 133/266mhz.

wot kind of damage could i have done running at 213 fsb, and 210 fsb, i then switched back to 200fsb?

[Austin]

If using dividers to set the PCI (etc) speed then I'll assume your mobo has the 1/6 divider designed for 200/400FSB.

200/400FSB 1/6 PCI=33.3mhz
210/420FSB 1/6 PCI=35.0mhz
213/426FSB 1/6 PCI=35.5mhz

So it shouldn't be damaging and should theoreticly be within the limits. If your system was stable but you got HD corruption it would most likely be your RAM producing the odd error at such a high speed and therefore corrupting things, otherwise it could simply be VIA's IDE implimentation not being suited to super high FSB (I'm assuming mobo chipset there). If you switch back to a FSB that your mobo (etc) are happy with then any damage is unlikely to be long term although you may have to replace the corrupt data where possible by doing a fresh install or repair for example.

its a nforce 2 ultra...so should be ok right?
